GEAR-ING.

Application led March 6, 1911.

Figure 1 is a part plan view of a meat slicing machine s owing the meat carrying platform and feed screw, Fig. 2, a section along the line 2-2 of Fig. l.

Like arts are indicated by like letters in all gures.

The machine base A is provided wlth the tracks A1 upon which is Slidably mounted the meat platform A2, provided with the upwardly extending elevating handles A3, the toothed uprights A4 and the upwardly projecting meat engaging spikes Af. The feed screw B is carried m the bearings B1 on the frame A and may be rotated by any suitable means not shown, by the shaft B2. The pivotally mounted arm B3 is provided with an extension or nut B at right angles thereto, having upon its outer edge the teeth I to engage the feed screw B and is provided with the outwardly projectin lug or linger B in opposition to the fixe lug B7 on the body of the platform. The slidable pin B8 is forced outwardly by the 'springB and has a beveled surface B10 in opposition to the lug B7 to lock the arm B3 in position. The lever 7i pivotally mounted on the top of the lug B7 and contains the curved cam slot C1 in engagement with the Screw or pin C projecting upwardly from the arm B3.

It will be evident that while I have shown in my drawings an operative device, still many changes might be made in size, shape and arrangement of parts without depart-- ing materially from the spirit of my invention and I wish therefore, that my drawings be regarded as in a sense diagrammatic.

The use and operation of m invention are as follows: With the parts in the position shown in full lines in Fi 1, the feed screw rotates responsive to t e transverse motion of the carriage not shown, and

draws the meat platform along the frame of the machine, thus feeding the meat on the carriage to the cutting knife. When it is desired to stop the movement of the platform without interrupting the feed screw, or when the platform has reached the end of its excursion, the hand lever is moved backward away from the feed screw drawing with it the arm and carrying the screw engaging nut out of engagement with the screw. The lug projecting from the arm comes in contact with the rlgid lug projecting from the platform and the lock bar engages the side of said lug removed from the screw as indicated in the dotted lines to lock the screw engaging nut out of engagement with the. screw. The meat carrying platform may then be removed by using the handles in the usual manner or may be moved back to the other end of its excursion without in any way disturbing the nut or the locking mechanism.

I claim:

1. The combination with a feed screw and a carriage parallel therewith and adapted to be driven thereby, of a lever pivotally mounted upon said carriage about an axis at right angles to the axis of the feed screw, provided with a feed nut projecting outwardly from one side thereof and meshing with the feed screw, a stop for said lever to limit its movement away from the feed screw, said lever being also provided with a finger projecting from the end thereof into line with the stop and yielding means projecting outwardly from the end of said lever into engagement with said stop.

2. The combination with a feed screw and a carriage parallel therewith and adapted to be driven thereby, of a lever pivotally mounted upon said carriage about an axis at right angles to the axis of the feed screw, provided with a feed nut projecting outwardlv from one side thereof and meshing with the feed screw, a stop for said lever to limit its movement away from the feed screw, said lever being also provided with a finger projecting from the end thereof into line with the stop and yielding means )rojecting outwardly from the end of sai lever into engagement with said stop, a controlling lever pivoted upon said stop and in slidable and rotatable engagement with the end of said feed nut carryin lever,

2i. The combination with 3 fgeed screw and n vari-lage parallel therewith and adapted to be driven thereby, of a lever pivotally mounted upon said carriage about an axis at right angles to the axis of the feed screw, provided with a feed nut projecting outwardly from one side thereof and meshing with the feed screw and yielding means for forcing said feed nut into mesh with the feed screw and manually operative means for withdrawing it against the pressure of 1g Witnesses:
